    Notes: [Auszug] In October 1962, a large number of semaeostome medusæ with associated phyllosoma larvse of Ibacus, at a late stage of development, were taken in a prawn trawl off Ballina, New South Wales, at a depth of three fathoms. The following evening a similar trawl in thirty fathoms yielded many ...

    Notes: Biochemical studies were carried out on a brain biopsy obtained from a 40 y old woman with homocarnosinosis. This patient and 2 of her siblings have a progressive neurological disorder characterized by spastic paraplegia, dementia and retinal pigmentation. Homocarnosine concentrations in their CSF, as well as in the CSF of their neurologically normal mother, are elevated 20-40-fold. Homocarnosine content was 4 times higher in the patient's frontal cortex than in biopsied cortex from a large group of control subjects. The activity of the synthetic enzyme, homocarnosine-carnosine synthetase. was not increased in the homocarnosinosis patient's brain. Homocarnosinase activity, however, was undetectable in the patient's brain biopsy, while it could readily be measured in comparable biopsies from control subjects. We conclude that homocarnosinase deficiency is probably inhcrited as an autosomal recessive trait, but that it is unlikely of itself to have caused the neurological syndrome affecting our patients.

    Notes: Abstract This paper reviews the marine living resources management practices in the ASEAN region. Lessons learned from past management of these resources are highlighted with an analysis of impacts. The lack of an appropriate management policy at national and regional levels, inefficient enforcement measures, the rapid population growth and unsustainable economic development have all contributed to the degradation of the resource base in the marine environment of many ASEAN members. The need to establish a holistic and integrated management approach as well as action plans to mitigate the accelerated deterioration of the marine environmental quality and to promote sustainable use of resources is strongly emphasized in this paper. Recent changes in government policies in ASEAN towards sustainable development could provide valuable opportunities to arrest further resource depletion. The ASEAN initiation of integrated management of marine resources is a step towards the right direction.
